RPL-1 Operation principle
The opening of the nozzle valve is controlled by solenoid valves and oil pressure. The
force of oil pressure on piston must exceed the force of the spring. The pressure of the
spring closes the nozzle valve, when oil pressure stops having effect on nozzle valve.
The needle valve of the nozzle closes. The needle in the nozzle valve is completely
drawn when oil pressure in control circuit is approx. 18 bar18 bar / 261 PSI261 PSI
(1800 kPa).
When to change nozzle
If nozzle is functioning improperly, clean nozzle with diesel oil. If cleaning does not fix
problem, nozzle has to be changed. New nozzle has to be of the same type as the
original.
If there is an oil leak from hole in rear cover, change nozzle or install a repair kit.
6.7 Oil regulator
Oil regulator function
When swing angle of servomotor shaft is in position 0º, dosing shaft is in open position.
Return flow is at the maximum, and return pressure at the minimum.
When swing angle of servomotor shaft is at its maximum 90º, dosing shaft is in closed
position. Return flow is at the minimum, and return pressure at the maximum.
● Pressure gauge on regulator shows return pressure.
● The size of the groove on dosing shaft is marked to shaft’s end.
